Description

Technical Field

[0001] This utility model provides a sealing device for refrigeration unit pipelines, belonging to the field of refrigeration unit pipeline sealing technology. Background Technology

[0002] Refrigeration units are indispensable equipment in modern industrial and commercial buildings, and their piping systems are responsible for transporting critical media such as refrigerants, cooling agents, or cooling water. The sealing performance of these pipes directly affects the operating efficiency, energy consumption, and safety of the refrigeration unit. However, existing pipe sealing devices still have significant shortcomings in practical applications and urgently need improvement.

[0003] Leak detection is one of the core issues in current sealing devices. During long-term operation, refrigeration unit piping leaks due to aging of sealing materials, loosening from vibration, or pressure fluctuations. When a leak occurs, water in the pipes can easily overflow into the unit, causing a damp environment around the equipment, short circuits in electrical wiring, and even safety accidents. Furthermore, traditional sealing devices lack intuitive leak detection methods, especially for small cracks and low leakage volumes, making it difficult to detect leaks quickly, further increasing maintenance costs and risks. Therefore, a new type of refrigeration unit piping sealing device is urgently needed to address these problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that there is often a lack of intuitive means of detecting leaks in refrigeration unit pipelines, and water can easily overflow into the unit when a leak occurs.

[0005] To solve the above problems, the proposed technical solution is as follows: a refrigeration unit pipeline sealing device, comprising an inner sealing pipe and an outer sealing pipe, wherein a first pipe and a second pipe are sealed together by the inner sealing pipe; the outer sealing pipe is disposed at the connection between the first pipe and the second pipe, and the inner sealing pipe is located inside the outer sealing pipe; a detection box is fixedly disposed inside the outer sealing pipe and located below the inner sealing pipe, and the detection box contains a detection reagent that changes color upon contact with water; grooves are formed on the inner walls of the first pipe and the second pipe, and two limiting blocks are fixedly disposed inside the inner sealing pipe, with snap-fit ​​components that snap into the grooves fixedly connected to the limiting blocks.

[0006] As an improvement, the downward projection of the inner sealing tube is located inside the detection box, and the detection reagent inside the detection box is white powdered anhydrous copper sulfate.

[0007] As an improvement, the outer sealing tube is provided with an observation window that allows the detection box to be observed, and the detection box is made of a transparent and observable material.

[0008] As an improvement, the outer sealing tube is composed of two half-shells spliced ​​together, and a connecting block is fixedly connected to the half-shells; bolt holes are opened on the connecting block, and the two half-shells are fixedly connected by bolts; a sealing gasket is provided at the splicing position of the two half-shells, and a sealing gasket is provided at the position where the half-shells contact the first pipe and the second pipe.

[0009] As an improvement, the snap-fit ​​assembly includes a connecting post and a snap-fit ​​block; the connecting post is fixedly connected to the limiting block, and the conical snap-fit ​​block is fixedly connected to the connecting post, and the snap-fit ​​block is snapped into the snap-fit ​​slot.

[0010] As an improvement, the limiting block, connecting post, and locking block are provided with through holes.

[0011] As an improvement, the first pipe and the second pipe are provided with sealing rings, and the inner wall of the inner sealing pipe is provided with a sealing groove corresponding to the sealing ring, and the sealing ring is located in the sealing groove; the position where the inner sealing pipe connects with the first pipe and the second pipe is coated with sealant.

[0012] The beneficial effects of this utility model are:

[0013] 1. The first and second pipes are connected by an inner sealing pipe, which is located inside the outer sealing pipe. By setting up two sealing pipes, the sealing performance can be increased. When the inner sealing pipe leaks, the leaked water can be contained in the outer sealing pipe, preventing the leaked water from flowing directly to the outside and reducing pollution. At the same time, a detection box is fixedly installed inside the outer sealing pipe, located below the inner sealing pipe. The detection box contains a water-sensitive detection reagent. When the inner sealing pipe leaks, the detection reagent changes color directly, which can be easily observed by the staff.

[0014] 2. The inner walls of the first and second pipes are provided with slots, and the limiting block is fixedly connected with a snap-fit ​​component that snaps into the slot; by setting the snap-fit ​​component, the pipe and the inner sealing pipe can be quickly installed and fixed, which greatly improves the installation efficiency of the inner sealing pipe.

[0023] like Figure 4 As shown, the inner walls of the first pipe 1 and the second pipe 3 are provided with slots 10. Two limiting blocks 11 are fixedly installed inside the inner sealing pipe 7, and snap-fit ​​components that engage with the slots 10 are fixedly connected to the limiting blocks 11. The snap-fit ​​components include a connecting post 12 and a snap-fit ​​block 13; the connecting post 12 is fixedly connected to the limiting block 11, and the conical snap-fit ​​block 13 is fixedly connected to the connecting post 12, engaging with the slots 10. By setting up the snap-fit ​​components, when the first pipe 1 and the second pipe 3 are connected to the inner sealing pipe 7, the snap-fit ​​block 13 engages with the slots 10, quickly completing the positioning and initial fixing of the pipes and the inner sealing pipe 7, improving the convenience and efficiency of installation. Through holes 14 are provided on the limiting blocks 11, the connecting post 12, and the snap-fit ​​block 13, ensuring that the normal connection between the first pipe 1 and the second pipe 3 is not affected.

[0024] like Figure 3 As shown, a detection box 6 is fixedly installed inside the outer sealing tube 2, located below the inner sealing tube 7. The detection box 6 contains a detection reagent that changes color when it comes into contact with water. The downward projection of the inner sealing tube 7 is located inside the detection box 6, which ensures that in the event of a leak, the water in the pipe can fall into the detection box 6. The detection reagent in the detection box 6 is white powdered anhydrous copper sulfate, which turns blue when it comes into contact with water, making it easy for staff to observe.

[0025] like Figure 2As shown, the outer sealing tube 2 has an observation window 5 that allows the detection box 6 to be observed. The detection box 6 is made of a transparent material, which allows for easy observation and detection of whether the inner sealing tube 7 is leaking without opening the outer sealing tube 2.

[0026] like Figure 1 , 2 As shown, the outer sealing tube 2 is composed of two half-shells spliced ​​together, and a connecting block 4 is fixedly connected to the half-shells; bolt holes are opened on the connecting block 4, and the two half-shells are fixedly connected by bolts, which facilitates the installation and disassembly of the outer sealing tube 2; a sealing gasket is provided at the splicing position of the two half-shells, and a sealing gasket is provided at the contact position between the half-shells and the first pipe 1 and the second pipe 3, which can increase the sealing performance of the connection between the outer sealing tube 2 and the two pipes.

[0027] The principle of this utility model

[0028] When using this application to seal the first pipe 1 and the second pipe 3, first install the inner sealing pipe 7, such as... Figure 4 As shown, the first pipe 1 and the second pipe 3 are inserted into the two ends of the inner sealing tube 7 respectively until the locking block 13 is engaged in the locking groove 10. At the same time, the end of the pipe contacts the limiting block 11, and the sealing ring 8 is located in the sealing groove 9. This completes the initial positioning and fixing of the inner sealing tube 7 with the first pipe 1 and the second pipe 3. Then, other fixing components such as bolts are used to completely fix the inner sealing tube 7, and sealant is applied at the connection between the pipe and the inner sealing tube 7.

[0029] After installing the inner sealing tube 7, install the outer sealing tube 2. Fit the two halves of the outer sealing tube 2 onto the first pipe 1 and the second pipe 3, so that the inner sealing tube 7 is located inside the outer sealing tube 2. Then, use bolts to securely connect the outer sealing tube 2 to the first pipe 1 and the second pipe 3. Figure 1 , 2 As shown. Figure 3 As shown, when the inner sealing tube 7 leaks, the outer sealing tube 2 prevents the leaked water from flowing erratically, thus providing a double-layer seal. At the same time, the leaked water from the inner sealing tube 7 can enter the detection box 6 and react with anhydrous copper sulfate, turning the anhydrous copper sulfate blue. Through the observation window 5, the staff can immediately observe the color change of the reagent in the detection box 6 and take appropriate measures.
